Read the following statements regarding the photon picture of electromagnetic radiation: A. The rest mass of a photon is zero. B. Photons are deflected by electric and magnetic fields. C. The equivalent mass of a moving photon of frequency is given by h c^2 . D. The energy of a photon increases when the intensity of incident light is increased. E. In a collision between a photon and a material particle, the number of

Options

  1. AA, C, D and E only
  2. BA, C and E only
  3. CA, B and C only
  4. DC, D and E only

Correct answer

B. A, C and E only

Step-by-step solution

Statement A is correct. The rest mass of a photon is zero. Statement B is incorrect. Photons are electrically neutral, so they are not deflected by electric and magnetic fields. Statement C is correct. The energy of a photon is E = h . Using Einstein's mass-energy equivalence E = mc^2 , the equivalent mass of a moving photon is m = h c^2 . Statement D is incorrect. The energy of a photon is determined by its frequency ( E = h ) and is independent of the intensity of light. Increasing the intensity of light increase
